Hi Nicola,

This is off topic, but maybe of some interest if you are familiar
with Tk and the /usr/bin/wish Tk shell. I remember that you mentioned
in the Squeak birthday celebration that you had loaded CommandShell
from https://github.com/dtlewis290/Cuis-Smalltalk-CommandShell.

CommandShell is not yet ready for use in Cuis, but parts of it do work
without issue, so you can try evaluating this:

	"PipeableOSProcess tkExample"

This opens a Tk window with some buttons, connected to your Cuis
image with a PipeableOSProcess.

I wrote this a long time ago and it has never been used for anything
useful, but maybe it is of interest anyway.
